True
The formula for probability is as follows:Probability = Total number of favorable cases / total number of casesIt always lies between 0 and 1 and has no unit.
When you calculate RF values, you need the distance moved by the dye (or whatever you're using) and the distance moved by the solvent (the eluent front) Given that no matter where the eluent front stops your measurement will always have the same standard error (say +- 1mm if you're using TLC plates and a normal ruler), then the further your eluent front and dye move, the less that measurement error will impact on your RF value - the error will be a smaller % of the overall distance.
Why the value of correlation coefficient is always between -1 and 1?
The range of a distribution is the difference between the largest number in the range and the smaller number. ?æThe number will always be positive, but may not always be whole.
why correlation cofficient always lies between 1 and -1
True
yes

It depends on what distance formula you are using!
Measurement always deals with a distance of a line or a distance between to objects, distance between 2 points, and so on.
The perpendicular distance between two parallel lines is always the same.
parallel lines - they are parallel when the distance between them remains constant
False.
Yes it is because they must have the same distance between them to be considered contour
yes it does
Formula of work is always { Work= Force x Distance} so you find the force applied and the distance moved then multiply
Not necessarily. The distance between (0.0) and (0.5, 0.5) = 0.7071 (approx).
